4. The method of claim 1, wherein after obtaining a preset number of preferred RIM neighbors, further comprising:

5. An apparatus for neighbor optimization, comprising:

the preferred RIM neighbor cell acquisition module is used for sequencing each RIM neighbor cell according to the priority of each RIM neighbor cell to acquire a preset number of preferred RIM neighbor cells;

the device for optimizing the neighbor cell further comprises an RIM neighbor cell determining module;

the RIM neighbor cell determining module 403 is configured to determine a RIM neighbor cell corresponding to the first cell;

the RIM neighbor cell determining module is specifically configured to determine whether a second base station with a common site exists in a base station corresponding to the first cell, where the base station is an LTE base station and the second base station is a UMTS base station;

if yes, acquiring a second cell corresponding to the second base station, and determining a plurality of 3G cells adjacent to the second cell as RIM (network information model) adjacent cells;

the priority obtaining module 401 is specifically configured to obtain the priority of each RIM neighbor according to the following formula one;

y is A.M + B.N + C.theta + D.P + E.T formula one
